To allwhom tmag concern,"

Beitknown that 1, Jaoon J LIBBY, a c ty zen of the United States ofAmerica,res1ding at Fostoria, Seneca County, Ohio, have inventedxnew anduseful Grain Doors, of

. which thefollowing is a specification.

This invention relates to closures of a readily removable type,. forloin openings or doorways.

This invention has utility when 1ncorporatedas a grain door forbox carsof railys-1 a,

4 Referring'to the drawings: Fig. 1 is a side elevation of car having;an embodiment of the invention incorporated therewith; Fig. 2 is a planview of'an assembled sectional unit;

Fig. 3 isa perspective view of the cleat carrying side of one of thesections of the section of the unit from that shown in Fig. 5 isafragmentary view on an enlarged scale showing in plan the'hook and seatengagement, as well as the button holdin g assembly features,

A railway box car 1 is shown as having a side doorQ slidable clear ofthe doorway or opening 3 having parallel sides 4.

A. door section 5 is shown as having a cross cleat 6 slightly spacedfrom an end 7 j provided with a pair of projections or hooks 9 todetachably engage with seats 10 in plates 11 anchored by rivets 12 tothe inner face13 of a second door section 14. This second section 14 hasa cleat 15 on its outer side, similar to the cleat 6 of the section 5,with door frame engaging points or prongs 8, also protruding therefrom,similar to the prongs 8 of the cleat 6. The two rows of seats 10 extendinward from the cleat 15, but upon the opposite side of thesection 14.Beyond these seats 10 and still more remote from the cleat 15, this doorsection 14 has a pair of parallel slots 16.

The first door section 5, isv shown as having a pair of pins 17 fasttherewith, provided with swiveled cross-barsorbuttons 18, which inprotruding after insertion through the slots 16, may be turned crosswiseof such a railway box 1 Fig. 4; is a perspective view of the other Idoor unit.

slots 16, and thereby readily serve as holding means for maintaining thetwo sections of the door unit in assembled parallel relation. Thehooks'9 as engaged in diflerent seats 10 provide a ready assembly meansfor varying the effective length of the unit to meet conditions ofvarying widths of doorways- In practice, when a car is cleaned out andready'to be loaded with grain, or other bulk material, a pair of unitsections are taken, the hooks9 being entered in seats 10in such regionthat as the slightly buckled sections are "forced into parallel relationwith'the' bethe'width adjustment, these button holding means may beturned for looking the lNith small or very fine bulk material,gunnyysacking or other backing may I be placed along the'door frame, thethreshold and between the units as built up, to such height as "may bedesired in closing the doorway. However in top groove 19 a rope-20 maybe partially embedded to project and seat-in bottom groove 21 of thenext section to packL-the joint. 'When the loaded car reaches itsdestination and it is desired to unload the same byyallowing thematerial to flow from the door, there is no occasion to mutilate the caror the door-units. In fact, the most ready way is to turn the buttons 18to align with the slots 16, and then with little effort the section 14;may be swung outward at an easily controlled rate for governing thedischarge stream, as the first section is also drawn outward by thehooks 9 still engaging the seats 10. This outward opening of the doorunit, automatically withdraws the points 8 from embedded relation.Assuming that this isthe lower door unit which has been removed, theflowing of the bulk material in discharge does not result in a topplingdown of the upper sections,'105 I which when built of wood and faced oriii' ing the sections together to approximate the width of the openingbetween the parallel sides thereof, when the sections are in-parallelrelation, there being a lock for said connecting means which in theadjustment of the sections is shiftable as to only one-of the closuresections.

2. A grain door unit'for railway box cars embodying a pair of sections,e'ach of less length than the width of the car doorway, and a hingeconnection between the sections :adjustably-and detachably unitingthesections, there being a lock for said connection mounted on one of thesections indevdependently-of shifting therealong.

3. A-doorsection having a projection, a

second door section having a series of seats engageable by the proect1on m ad ust1ng the assembly of the sections to different widths ofdoorways, said sections being provided with embedding means for engagingopposite sides of a door trame and means adjustable along one-oi": saidsections only for drawing the sections in position against disengagementof the projection from a seat and simultaneously mounting the sectionsin the frame by driving the engaging means into the frame. i

4. A door section having a terminal project-ion, a second door sectionhaving a row of seats which in setup position of the section extendtransversely of a doorway, said sections being provided "with embeddingmeans vtor engaging opposite sides of a door frame, and means carried bythe projection carrying section adjustable along one of said sectionsonly for drawing the sections assembled in parallel relation with theprojection engaging a and simultaneously mounting the-sections in theframe by driving the engaging means into the frame.

5. A sectional grain car door unit embodying a-pairof hinge connectedse'ctions having their remote ends provitiled with cross cleats spacedinwardly i'romsuch ends, anddoorway frame engagingprongs carried by saidsect-ions adjacentsaid cleats, said pair of sections being adjustabletor Width, and a lock for the hinge fixed as to onev of said sections. a

6. A rain car door unit embodying a pair of sections for assembly witheach other and each provided with a cross cleat spaced from the outerend thereof, the other end of one of said. sections being provided witha pair of hooks, the other sectionbeing providedwith two rows of'seatsextending away irom its cleatand engageable by the hooks in assemblingthe sections into parallel'relation to have the cleats approximate adoorway width and the projections beyondthe cleats engage a doorframe onthe inner side, said seat carrying section having more remote from itscleat than said seats, apair of slots, and buttons carried by the hookcarrying section to protrude through said slots and shittable to lockthe sections .in parallel relation, and releasable from outside the doorfor outward swinging of the door in door unit removal.

In witness whereof I aflix my signature.
